Abstract
The present invention relates to a manufacturing method for an orifice plate to be used for an ink jet printer or the like. First, a master having a predetermined pattern firmly provided on a substrate is prepared. An electroformed film is then formed on the master by an electroforming method. Finally, the electroformed film is separated from the substrate. In this case, the mask pattern is firmly provided on the substrate, and a mechanical strength of the mask pattern itself is large. Furthermore, the mask pattern is insoluble to an alkali aqueous solution. Thus, the master can be reused, and it can be strongly washed. Accordingly, the master has a durability to repeated usage, thereby contributing to an improvement in the quality of the orifice plate to be manufactured and a reduction in the manufacturing cost.
